"Once running and up to pressure the air compressor will cycle infrequently"
The compresssor works all the time only RPM's effect the rate.
Thats why the systems have dump (pop off) valves, when the system reaches the set air pressure it dumps air and builds again.
So anyway there is only a pressure regulator and it runs all the time.
